If I am reading this correctly, you will be a full time student in fall 2016, and spring 2017…graduating at the end of that spring term. Is that correct?
If so, any overage from fall term will be refunded to you sometime during the fall term. Any overage from spring term will be refunded to you during the spring term.
The money is YOURS. Contact YOUR school to ask about refunds…when they are done…and how. Some schools will only direct deposit into your bank account. Some will,send a check.
Some schools will allow you to charge your textbooks…and use your refund to pay that bill. You can ask about that too.
